Woman auctions tattoo space on backside

A cash-strapped New Zealander is auctioning off the chance to put a tattoo on her derriere so she can pay her bills.

Wellington woman Tina Beznec, 23, says she needs the money after being made redundant twice in the past year.

She set up an online auction under the title "Your Tattoo on my Bum" and within 24 hours bidding had reached NZ$10,250 (US$8,135) while another three people have followed suit with auctions offering body parts to be tattooed.

"You might think I am crazy for doing this! But yes, the winner of the auction gets anything they like tattooed on my bum!" Beznec said in her auction notice.

She said 20 percent of the winning bid would go to charity "and the rest will go to me, I deserve it, I have been made redundant twice over the past year."

The tattoo would be 9x9 centimetres (3.5x3.5 inches), it could be on either cheek and could be something personal or "a business promotion" she said.

"The way I see it is it's going to be on my bum and it is something I can look back on in the future and remember this point in my life," she told the Stuff.co.nz website.

In a rival auction, a woman who identified herself as "Marie" said she decided to copy Beznec's money-raising scheme because "I'm a single Mum struggling just to pay the bills".

S. J. Parker said he was auctioning his backside for a tattoo because "I was laid off myself at the end of the year so have mounting bills. I've been offered a job teaching overseas shortly so got to get that airfare somehow."
